Marine Doom is a bad mod for Doom II, that is a single-level PWAD. The mod was made for use by the US Marines. In 1996 the mod was made available for public download thanks to Sergeant Daniel G. Snyder.
In the game, a fireteam, comprising four Marines, is supposed to accomplish a specific mission, the default being the destruction of an enemy bunker. In order to allow coordination of their movements, these soldiers play on separated computers in the same room. The fireteam consists of a Team Leader, two riflemen, and one machine-gunner.
Marine Doom was later superseded by the completely homebrew game America's Army.
